In a few cases you have a choice. Remember that a smaller magnitude number is a brighter star, if that is your preference.
Name: 7 Delta CRV (Corvus) Algorab
Birthday from Jack’s initial research: Sep 30
Magnitude: 3.0
Spectrum/Star type: Blue
Distance in Light Years: 88
Diameter compared to Sun: ~2
Luminosity compared to Sun: 48
Date best observed: May 14
Additional information: “The Raven”, an easy attractive unequal double in a small scope. It is outside of the zodiac. With Eta CRV just above it, Delta marks one of the 4 corners of The Crow’s square-like shape. (Bright Spica in Virgo is about 10 degrees to the left).
Name: 8Eta CRV (Corvus)
Birthday from Jack’s initial research: Oct 1
Magnitude: 4.3
Spectrum/Star type: Light yellow
Distance in Light Years: 59
Diameter compared to Sun: 1.5
Luminosity compared to Sun: 5
Date best observed: May 14
Additional information: 8 Eta is just beyond the zodiac. It has a disk of debris around it – could be planets forming or a comet belt like our Kuiper Belt. This star is younger and more massive than the sun. It is a naked-eye double with Delta.
